The violent 30-year-old pimp had executed Halifax teen Kelly Wilneff, 17, with 10 bullets in the head for planning to testify against him at his assault trial, according to CBC News archives.

As for Magnotta, he’s serving a life sentence for the lurid murder of a Montreal student in 2012. The former low-rent porn actor killed and dismembered his Chinese victim.

The newsome twosome’s marriage will be celebrated at the Pont-Cartier Penitentiary under strict conditions, TVA Nouvelles reports.

The hopeless romantic said he was seeking a “prince charming” who was white, in good shape between 28 and 38 years old.
